Claim of US Patent No. 10,924,273

1. A computer-implemented method for secure multi-party computation (MPC), comprising:receiving, by a first electronic device from a server in communication with a second electronic device, a first random seed, a second random seed, and a first random number set;
generating, by the first electronic device, a second random number set and a third random number set based on the first random seed and the second random seed respectively; and
performing a secure MPC process with the second electronic device using the first random number set, the second random number set, and the third random number set,
wherein the server provides a third random seed, a fourth random seed, and a sixth random number set to the second electronic device, and
wherein random numbers in (i) the first random number set, (ii) the second random number set, (iii) the third random number set, (iv) a fourth random number set generated by the second electronic device based on the third random seed and the fourth random seed, (v) a fifth random number set generated by the second electronic device based on the third random seed and the fourth random seed, and (vi) the sixth random number set satisfy a predetermined condition.
